The intrusion is the largest of a set of 100's mafic-ultramafic bodies found within the Curaca Valley terrain, a N-S trending strip of high-grade rocks in the northern part of the Sao Francisco Craton. This terrain comprises of supracrustais and gneisses of their probable basement, the mafic-ultramafic rocks emplaced as sills, all intruded by G1-G3 early- to late-tectonic tonalitic-granodioritic orthogneisses and granites related to highly ductile deformation events between 2.25 to 2.05 Ga (U-Pb ages of zircons).
